RegGuard — AI Compliance Co-Pilot for VS Code
RegGuard scans your code against real regulations for your product type, release regions, and tools — and flags issues with line-level precision. Accept or decline Claude's proposed fixes without leaving your editor.
How it works
- Perplexity searches for current regulations applicable to your product, regions, and tools
- Grok surfaces trending and upcoming regulatory changes in the next 6–12 months
- Claude reads your code, flags non-compliant lines/blocks, and proposes drop-in fixes
All three models are accessed through a single OpenRouter API key — no separate subscriptions needed.
Setup
1. Get an OpenRouter key
Sign up free at openrouter.ai and copy your API key.
Open VS Code Settings (Ctrl/Cmd + ,) and search for regguard:
| Setting |
Example |
regguard.openRouterKey |
sk-or-v1-... |
regguard.productType |
"fintech mobile app" |
regguard.releaseRegions |
["EU", "US", "UK"] |
regguard.clientRegions |
["EU", "US"] |
regguard.externalTools |
["Stripe", "Twilio", "AWS S3"] |
regguard.internalTools |
["React", "Node.js", "PostgreSQL"] |
regguard.scanOnSave |
true or false |
3. Scan
- Command Palette →
RegGuard: Scan current file
- Right-click any file →
RegGuard: Scan current file
- Sidebar → Click the shield icon → click Scan
- Auto → Enable
regguard.scanOnSave to scan on every save
Using findings
Flags appear as squiggly underlines just like ESLint errors. You can:
- Hover over the squiggly to read the regulation and issue summary
- Click the lightbulb (or
Ctrl/Cmd + .) to open the quick-fix menu
- Apply fix — Claude rewrites the flagged block in place
- Decline — dismiss the flag
- View details — opens a full regulation panel beside your editor
The RegGuard sidebar (shield icon in the Activity Bar) shows all findings across all open files with jump-to-line and apply-fix buttons.

Regulation cache
Regulations are cached for 30 minutes to save API credits. If your product config changes, use RegGuard: Refresh regulations cache or change any setting (the cache clears automatically).
Cost estimate
A typical scan uses approximately:
- ~2 000 tokens (Perplexity) — regulation fetch
- ~1 500 tokens (Grok) — trending fetch
- ~3 000–8 000 tokens (Claude) — code analysis, scales with file size
On OpenRouter free tier / pay-as-you-go this is a few cents per scan. Regulation results are cached for 30 minutes so repeated scans of different files only re-spend the Claude analysis tokens.
Privacy
Your code is sent to Claude via OpenRouter. Regulations context is sent to Perplexity and Grok. Review OpenRouter's and each model provider's privacy policies before scanning proprietary code.
